HEATING-STOVE.

Application filed July 14,

T 0 all whom it may concern Be it known that I, RowLnY RonINsoN, acitizen of the United States, and a resident of Camas, in the county ofClark and the State of VVashing-ton, have invented a new and usefulImprovement in Irleatingfitoves, of which the following is aspecification.

My invention relates to improvements in stoves such as are used forheating air, either as a stove to be located in the room to be heated oras a so-called hot-air furnace such as are used for heating air which islater circulated t0 the room or rooms where needed. The object of myimprovement is to 111- crease the effectiveness of the heating surfaceof the stove and so improve its efficiency.

The invention is illustrated in the accompanying drawings, whereinFigure 1 is a perspective view of a stove or heater constructed inaccordance with my invention;

Fig. 2 is a longitudinal vertical sectional view thereof;

Fig. 3 is an enlarged fragmentary vertical sectional view through one ofthe radiation drums or casings;

In these drawings, I have illustrated a combinated cook stove andheating stove, and in this construction I have embodied a longitudinallyextending, hollow body 10, from one end of which there extends upward acasing or drum 11, within which is disposed a grate 12 and an ash pan13, the grate 12 being at the bottom of the fire pct 14. The front wall15 of this casing or drum is provided with an opening to the fire potand an opening to the ash pit from which the ash pan may be withdrawn,these openings being closed respectively by a door 16 and by the end 17of the ash pan. A damper 18 is disposed below the grate 12 whereby airmay be admitted to the grate. The top of the drum 11 is formed withopenings closed by stove lids 19. Extending upward from the body 10 at aplurality of spaced distances and opening at the lower ends into thebody 10 and practically forming part thereof are the radiation drums 20.Extending upward from the bottom of the body 10 and into each radiationdrum and spaced from the side walls thereof are the baflie plates orwebs 21 so disposed that they cause the hot gases and products ofcombustion passing from the fire box to pass up ward into each of theradiation drums sue Specification of Letters Patent.

cessively and then downward into the body and then into the nextradiation drum. The end wall of the stove is provided with the largeoutwardly projecting collar 22 whereby a pipe may be connected to thestove.

It will be noted that the fire pot 14 is spaced from the outer wall ofthe drum 11 so as to leave a passageway l1 leading into the body belowthe ash pit and that from thence the products of combustion pass alongsuccessively through the several chambers or radiation drums 20 untilthey pass out through the flue collar 22.

While I have illustrated two drums 20 and one drum 11., I do not wish tobe limited to the number of drums 20 which may be used, as the number ofthese drums is limited by the size of the stove and the heat desired.Neither do I wish to be limited to the positioning of the heating drum11 at one end of the stove, though this is preferable. It will be seenthat the partitions or baffles 21 and the fire pot 1a are so arranged asto cause the products of combustion to take a circuitous course inpassing through the stove so that a large part of the heat is radiatedinto the room from the several drums 20 before the products ofcombustion pass out through the flue. It is further to be noted that byarranging the drums 20 in spaced relation to each other, spaces 20 areleft between the several drums 11 and 20, by which the air in the roomis brought in close contiguity with the heated drums. Of course, thedraft is to be regulated in the usual manner by the damper 18 and by adamper in the stove pipe (not shown).

While I have illustrated this device as forming a combined cook stoveand heating stove, yet I do not wish to be limited to this, though Iregard it as preferable, as a stove to be used entirely for heatingmight be constructed upon the same principal or it may be used as aso-called hot air furnace.

In order to provide means whereby the draft may be increased whilestarting a fire, I have illustrated the baffles 21 as being verticallymovable from a position on the floor of the stove to a raised positionfrom the floor so that the products of combustion may pass directly fromthe heating drum 11 to the flue. This permits one or more of thesebafiies to be raised to thereby control the draft when the fire isstarted. It also permits these bafiies to be raised so as to permit thebody to be cleaned out. To this end, I

mount each baflie in its corresponding radiation drum between inwardlyprojecting lugs or other guides 23 which may be riveted to the end wallsof each radiation chamber, and I attach to each baffie plate an upwardlyextending rod 24: extending out through the top of the radiation chamberand having a handle whereby the battle may be raised or lowered.Preferably these rods 24 extend out through tubular guides 25 attachedto the upper face of the radiation chamber, which guides may haveasbestos packing therein to prevent the escape of combustion gases andthese guides carry means, as for instance an ordinary'latching device,26 embodying a clamp by which the rods 2% may beheld in any adjustedposition. Of course,

I do not wish to belimited to the details 01- being formed with aplurality of upwardly extending, radiation drums opening into the bodyand spaced fronreach other whereby air may-pass between the drums, andbafile partitions extending upward from the bot torn oi the body intosaid radiation drums and nearly to the upper ends thereof whereby tocause the products of combustion to pass successively through theseveral drums, said bailles being vertically shil'table independently ofeach other.

2. A heating stove or furnace comprising a body formed with a pluralityof outwardly extending radiation drums opening into the body and spacedfrom each other whereby air may pass between and around the drums, thebody having an inlet at one end and an outlet at the other end, andbafile partitions extending from the outer wall o1" the body into saidradiation drums nearly to the outer ends thereoi, whereby to. cause theproducts of combustion to pass successively through the several drums,said'ballie partitions being longitudinally shiftable Within the drumsin each other.
